Spin-up

Was a spin-up performed?: Yes

Spin-up design: Spin-up experiments have been done for 1851-1900 using cycling climate forcing from 1901-1910 and transient CO2 conditions.

Natural Vegetation

Natural vegetation partition: For each grid, SSiB4/TRIFFID-Fire simulates the fraction of 7 plant functional types (PFTs) + the bare soil: BET: Broadleaf evergreen tree NET: Needleleaf evergreen tree DBT: Deciduous broadleaf tree C3: C3 grass C4: C4 grass SHR: shrub TUN: tundra shrub

Natural vegetation dynamics: In each grid, the fraction of each PFTs is updated every 10 days related to the Net Primary Productivity

Soil layers: 3 layers

Soil

Soil layers: 3 layers

Routing

Runoff routing: No

Land Use

Land-use change effects: Cropland changes

Dams & Reservoirs

Dam and reservoir implementation: No

Calibration

Was the model calibrated?: No

Vegetation

How is vegetation represented?: We consider the dynamic fraction cover of the following PFTs BET: Broadleaf evergreen tree NET: Needleleaf evergreen tree DBT: Deciduous broadleaf tree C3: C3 grass C4: C4 grass SHR: shrub TUN: tundra shrub
